Abstract
This study was performed in second half of year 2009.For bird counting , monthly from Septamber until March 2009. Total counted birds in Maroon lake were (971). Maximum number of counted birds was in February (191) and minimum of counted was in Septamber (95). Total counted birds in Jaizan were (385. Maximum number of the counted bird was in February (84) and minimum of counted (52) was in Januarry. Comparision of density of waterfowl and wader birds between Maroon lake and Jaizan lake shown that density was in Maroon was (0.48) bird per hectar and in Jaizan was 3.20 bird in hectar in during study time. Density maximum in maroon lake was (0.09) bird/hectar while it was (0.7) bird/hectar in jaizan lake in February. The density minimum in maroon lake was (0.04) bird/hectar in March while it was (0.4) bird/hectar in Jaizan lake in January. According to Morrista index, maximum difference between two lakes was (0.33) in January and maximum similarity was (0.64) in February. It is concluded that biodiversity and density waterfowl birds and waderbirds in compare with natural lakes were very low. That is seems that difference factors such as depth lake, poor vegetation cover, continuous change in water depth, large slope in border zones and unsuitable quality of water have important role in this matter but since these limitation were less in Jaizan. the diversity and density index were higher in compare with Maroon. conservation effect on the biodiversity and density indexes by regression tests shown that the conservation effect on the biodiversity and density of waterfowl and waderbirds between Maroon lake in the protected area and the Jaizan lake was not significant (p-value=0.059)
